1) Install the gnome-alsamixer package.2) In GNOME ALSA Mixer, increase the values of the Internal Mic and the Internal Boost.3) Select the internal mic as the recording device.

Note: This may not work for you. I am unable to know due to scepticism.

I have been trying for the last while to get my webcam and microphone working on my laptop and, after getting the webcam to work, all I need yet is to get the mic functioning. Unfortunately, I really have no idea how to do this.

In alsamixer, it includes three sound cards: PulseAudio, Conexant CX20585, and the HDMI card. PulseAudio is the default and includes no mic setting. Conexant does, however. I am thinking that I need to set this to the default, but again, I have no idea how to go about this.

Have you installed the gnome-alsamixer package? What is the model number of the Toshiba laptop? If you have gnome-alsamixer installed, check the level of the microphone and put a checkmark on the box next to "Mix". On my systems, Audacity doesn't record unless I put a check next to "Mix".
